(Cl. 24S- 201) 6 Claims.

My invention relates to means for mounting a casing or other device`substantially centrally oi" a vehicle wheel.

I have illustrated my invention in connection with mounting a tireiniiation alarm such as is illustrated in my Patent No. 2,056,064,granted September 29, 1935, for which purpose it is particularly useful,but it will be understood that its use is not conned to mounting suchalarms.

This application is a substitute for abandoned application Serial No.165,029, filed September 22, 1937, and allowed September 24, 1938.

It is the primary object of my invention to provide a mounting devicewhich can be adjusted quickly and effectively to t wheels of diiierentsizes and engage the wheels securely.

It is another object to provide a mounting device which can be quicklyapplied to and removed from a wheel and can `be locked to the Wheel whenapplied.

It is a further object to provide a mounting device having means topermit radial adjustment to iit Wheels of different sizes and axialadjustment to accommodate various rim conditions.

A further object is to provide a mounting devi-ce with resilient meansto absorb road shocks and prevent undue shock to the device which isto-be mounted.

I have illustrated my invention in the preferred form in theaccompanying drawing, wherein:

Figure 1 is an elevation of a wheel showing the mounting device used tomount a tire inflation alarm; i

Figure 2 is a side view of `the device looking toward the left in Figurel, the Wheel and tire being diagrammatically shown in dot and dashlines;

Figure 3 is an enlarged section taken substantially on the line 3-3 ofFigure 1; l

Figure 4 is a fragmentary view of the end of the arm shown in Figure 3,a portion being shown in cross-section;

Figure 5 is airagmentary section taken substantially on the line 5-5 ofFigure 4;

Figure 6 is a fragmentary section taken'on the line G- of Figure 5; and

Figure '7 illustrates a modiiied arm construction.

Referring to Figure 1, reference numeral 1 indicates the casing oi thetire alarm device which is connected to the tires by means of tubes-8one of which leads to one tire and the other to the second tire.

Three arms extend radially from this casing 55 turned.

and at the outer end each arm engages the rim 9 o i the wheel.

Two of these arms Ill-I0 are of identical construction but the third armII has some additional features not found in arms I0.

Referring to Figure 3, it will lbe seen that the arm 'I consists of thetubular member I2 secured to casing l, a smaller tubular member I3 whichfits and slides within tube I2 and a head or end member indicated as awhole by reference letter The tubular member I2 is provided with a boltI5 which extends through the tube. The tubular member I3 is providedwith a series of holes v I4 and an approximate extension of the arm toproper adjustment is secured fby sliding the tube I3 in the tube I2,until the desired hole Ill registers with the holes of the lbolt I5. Thebolt I5 is then inserted through the aligned holes and holds themem-bers I2 and I3 xed in desired position. The construction of arms IDissimilar to arm Il in this respect.

In arm II the head A comprises a member IB having a tubular portionI'I," a saw tooth face I8, a cooperating angle plate or lug I9, and aresilient pad 2U. The tube I3 fits and slides within the tubular portionI'I of the head and is prevented from sliding out by means of the pin 2I which is mounted in the tubular portion Il and extends through slotsr22 in tube I3. There is also mounted in tubular portion II a cani 23which may be keyed to a pin having bearings 24 in opposite walls of thehead, one of the said bearings extending beyond the wall and terminatingin a squared end 25 to which a wrench can be applied to turn the cam.One side of the head at this bearing also has a thickened wall 28 toprovide room for mounting the lock 25. This lock has a spring pressedpin 21 in the bearing 2li which engages the wall 28 to prevent turningof the cam 23 when it is in the position illustrated in Figs. 5 and 6.The pin 27a, which engages the end of the pin 21, is moved in and out ofthe lock 26 by turning the key 26a. When the pin 21a is moved outwardlyit forces the pin 21 against the spring until the pin no longer engagesthe wall r28. The bearing 2li is then free to turn. Movement of the pin21a in the oppositedirection allowsl the spring to force the pin Z'Iinto engagement with the bearing 28 whenever the pin registers with theopening in the wall 28 in which the pins slide. The tube i3 has a closedend 29 against which cam 23 bears when it is The angle plate or lug I9has teeth on one face to engage the teeth on face I8 and is alsoprovided with an upturned portion 3|! to engage the wheel and positionthe mounting axially with respect thereto. The plate I9 is secured tothe member I6 by means of a screw 3| which passes through the slot 32 inplate I9. By loosening the screw 3| the plate I9 may be lifted out ofengagement with the'member IB and moved in a plane parallel to the axisof the wheel with respect to the arm I I in order to locate the arm I Iproperly with respect to the wheel. When properly adjusted, the screw 3|can be tightened and will hold the parts in ilxed relation.

A resilient pad 20 of rubber or like material is placed on the outerface of the plate I9 and engages the rim of the Wheel when the device isin use. This pad absorbs road shocks when the device is in use and alsoserves another purpose to be pointed out hereinafter.

The arms I differ from the arm in that they are not provided with thecam and sliding connectibn between the head A and tube I3. In the arm I0the head A is held in permanently xed relation to the tube I3. Otherwisearms I0 and I are the same. l

In applying the mounting device and'alarm to the wheel the arms arefirst extended to approximate t by moving the tubes I3 in the tubes I2until the appropriate holes I4 register with theholes for bolts I5. Itis desirable to have the extension the same in each arm if possible sothat the alarm casing 1 will be as centrally positioned as possible. Theplate I9 is adjusted with respect to the member I6 to secure the bestaxial position for the casing l. When applying the device to the Wheelthe cam 23 is turned so that it is out of contact with the end 29 oftube I3, but after the mounting has been properly adjusted andpositioned in the wheel the cam 23 is `final position the arms IIJ andIIwill be forced into secure engagement with the wheel. The carn 23 isthen locked in position to prevent accidental turning and also toprovide protection against unauthorized removal of the mounting.

In the modified arm construction shown in Figure 7 I have provided aplurality of steps on the end of the tube |3a having curved seats |3badapted to contact a pin |213 carried by the tube |2a. In this instancethe tube I2a may be rotatably mounted in the casing l and when thedevice is applied to a wheel the tube |3a is moved in or out to effectthe desired adjustment and the tube I2a rotated to suit. Since the seatsI3b are1 curved it will be seen that when the cam 23 is adjusted tolocking position the curved seats are forced tightly against the pins|2b to prevent accidental displacement.
